Cumberland falls state park
I hadn't been here before and unfortunately our campsite was kind of the worst. It was gravel and full sun the entire day. Cumberland falls is ok, it is super crowded, and as another reviewer mentioned there is tonssss of trash. Personally I highly recommend visiting eagle Falls, another waterfall at the park. It's a tough trail to get there but way worth it. Plus you can swim there. All in all the trails are great, the campground not so much.
Also one of the workers tried to tell us we could walk our kayaks to the bottom of Cumberland Falls and head out from there, and no, no you cannot.
